Anqing Anqing carbon fiber reinforced carbon fiber reinforced school Anqing Anqing plant carbon fiber reinforced fire room through reinforcement professional reinforcement company Shanghai city construction reinforcement reinforcement methods including carbon fiber reinforced carbon fiber and CFRP reinforcement two kinds. Carbon fiber reinforced materials for the repair of concrete structures began in the 1980s the United States, Japan and other developed countries. The technology of our country started late, but with the rapid development of China's economic construction and transport services, a considerable portion of the existing building design load criteria was low because the historical problems caused by some changes in the function of the use of the building, it is difficult to meet The current specification needs to use the urgent need for repair, reinforcement. There are many commonly used reinforcement methods, such as: increasing section method, Outsourcing Steel Reinforcement, bonded steel reinforcement, carbon fiber reinforcement method. Carbon fiber reinforced structural repair technique is the second increase the concrete section, and a new structure after bonding steel reinforcement technology considerations; 1, carbon cloth as a conductive material, the construction should stay away from electrical equipment and power supply, or take protective measures and reliable . 2, the construction process should be avoided carbon cloth bent. 3, CFRP supporting resin should be stored away from ignition sources and avoid direct sunlight. 4, the resin formulation and use of space, should be kept well ventilated. 5, on-site construction personnel shall take appropriate measures to protect construction preparation work to develop construction plans and construction plans to deal with carbon fiber sheets are used, supporting resin, equipment and other preparatory work done before construction. Concrete surface treatment to clear the surface of the reinforcing member is flaking, loose, cellular, corrosion deterioration of concrete, exposed concrete structure layer and the surface repaired with prosthetic material flat. According to the design requirements of the cracks pouring or closed treatment. Preparation and brushing the underlying resin craft regulations formulated by the underlying provider resin, the resin evenly on the bottom surface of the concrete. After the resin surface dry to touch on to the next step of the construction immediately. Leveling and preparation of materials for repairing uneven concrete surface at leveling material to fill the recessed area with flat corner leveling application materials to repair a smooth arc. Paste carbon cloth / Kevlar fabric ① cut to size according to the design requirements of the carbon cloth / Kevlar cloth; ② formulated resin impregnation and paste evenly on the desired component; ③ rolled several times along the fiber direction, in addition to squeeze bubbles, resin impregnated fully saturated with carbon cloth / Kevlar cloth; ④ carbon cloth / Kevlar fabric impregnated with resin surface evenly. Surface protection required by the relevant norms of treatment, and to ensure a reliable bond between the protective material and carbon cloth / Kevlar cloth. Second, the application performance: 1) drained steel reinforcement 2) beams, columns breaking reinforced construction reinforcement applications Picture 3) plus seismic reinforcement layer 4) elevated, bridge maintenance and reinforcement 5) shear reinforcement door 6) A reinforcement balcony root fracture light weight, can operate in a small space, the use of high-strength construction process unaffected B, can be used in engineering structures and flexible bending, shear and compression of C has excellent flexibility, can be wrapped in a complex shape components D meet a variety of component surface (bridges, tunnels, panels, beams, columns, ventilation barrels, pipes, walls, etc.) of alkali chemical resistance requirements of E can reuse the fabric covering the flat; little impact on the decoration, storage life long; allow long operating period before the operation, and after the operation are allowed to operate there are some differences F high temperature environment, creep resistance, wear resistance, good seismic performance of CFRP Products, also known as carbon fiber cloth, carbon fiber cloth, woven carbon fiber, carbon fiber prepreg and carbon fiber reinforced cloth, carbon cloth, carbon fiber fabric, carbon fiber tape, carbon fiber sheet (prepreg) and so on. Carbon fiber reinforced fabric is a unidirectional carbon fiber reinforced products, usually woven 12K carbon fiber thread. Available in two thicknesses: 0.111mm (200g) and 0.167mm (300g). Variety of widths: 100mm, 150mm, 200mm, 300mm, 500mm width required for special projects and other. Tensile for structural members, shear and seismic reinforcement of the material used in conjunction with ancillary become impregnated plastic carbon fiber composite materials, can constitute a complete high performance CFRP sheet enhancement system for use in processing building load increases, Works using functional changes, material aging, concrete strength less than the design value, structural cracks treatment, harsh environment service component repair, protection of reinforcement. Features high-strength, low density, thin, almost no increase in weight and cross-sectional dimensions of the reinforcing member. Wide application, widely used in various types of building bridges, tunnels and other structures, structural repair and reinforcement of structural shape of seismic strengthening and reinforcement of nodes. Convenient construction, no large-scale machinery and equipment, no wet work, no flare, no fixed site facilities, construction occupies less space, construction efficiency is high. High durability, because not rust, ideal for high-acid, alkali, salt and atmospheric corrosion environments. Scope for a variety of structural types, structure of the various parts of the reinforcement structure repair, such as beams, plates, columns, roof trusses, piers, bridges, cylinder, housing and so on. Suitable for reinforcement and seismic reinforcement works in reinforced concrete structures, masonry structures, wooden structures, especially for complex forms of surface and node structure of port engineering and hydroelectric. Grassroots strength concrete requirements of not less than C15. Construction of the ambient temperature in the range of 5 ~ 35 ℃, relative humidity less than 70%.
